Just because DnD purists want a videogame simulator of the rules they obsess over doesn't mean that the majority of casual players will like it.
Out of curiosity, where are you seeing these "DnD purists" who "want a videogame simulator of the rules" and who "obsess over" said rules. I'm interested to know where you're interacting with people like that, because there certainly aren't any of those kinds of folks around here... in which case, you should probably leave your denigrating language out of posts you make here, where such people aren't really present to defend themselves.
